binnding RMIDispatcher to client

[David E Jones-2]

One trick with this: it is a good temporary fix, but not something I  
think we'll do in the project because it is tough to remember to  
manually change it each time the fields (or the data structure in  
general of the class) change.

Hello,

http://java.sun.com/j2se/1.5.0/docs/api/java/io/Serializable.html

"However, it is _strongly_recommended_ that all serializable classes
explicitly declare serialVersionUID values, since the default
serialVersionUID computation is highly sensitive to class details that
may vary depending on compiler implementations, and can thus result in
unexpected InvalidClassExceptions during deserialization."
